Abstract

The utility model discloses a gas range with timing function, comprising a timer circuit which consists of a power supply, a switch controlled by the timer and a loop in the solenoid valve of the power supply, connected in serial, wherein the solenoid valve of the power supply is arranged between the air inlet of the gas range and the air intake of an on-off valve. The utility model adds a timing switch device in the gas range, once the user needs to leave the gas range which is used for cooking, only need set a rated time, even through the user forgets that the gas range is used, when the rated time arrives; the utility model automatically closes the gas duct without unthinkable result, in particular to some work which needs given time to cook, such as medicine boiling and extractive, etc. The utility model saves the user from anxiety.

Description

Gas-cooker with timing function

Invention field

The utility model belongs to a kind of household gas utensils, relates in particular to, a kind of gas-cooker with timing function.

Prior art

Existing gas-cooker does not all have timing means, and kitchen range had an accident in the past, mostly because of the user leaves the kitchen range that using for a long time, causes firing fire and extinguishes, and combustion gas is excessive.

Summary of the invention

The utility model is to realize like this, a kind of gas-cooker with timing function, it is characterized in that, described gas-cooker comprises a timer circuit, described timer circuit is formed by the series connection of the coil in power supply, timer-operated switch, the power supply magnetic valve, and described power supply magnetic valve is arranged between kitchen range air inlet and the switch valve air inlet.

Goal of the invention of the present utility model is, on gas-cooker, add a regularly shutoff device, in case need leave just when the kitchen range of cooking food, as long as set a time rating, even forgetting gas-cooker uses, expire time rating, closes gas circuit automatically, can not cause unthinkable consequence.Especially need special time to fire to some, as boil medicine, the work of extractive and so on, use this kitchen range to save worry more and relieved.

Description of drawings

Below in conjunction with accompanying drawing the part utility model is further specified, the person skilled in art can be to structure of the present utility model, the clearer understanding of feature and advantage according to following narration.

Fig. 1 is that magnetic valve is provided with position view;

Fig. 2 is solenoid valve control circuit figure;

Gauge tap structural representation in Fig. 3 timer;

Fig. 4 provides a kind of circuit diagram that has the gas-cooker of igniting again and timing function simultaneously;

Fig. 5 is the vertical view of the utility model gas-cooker.

The specific embodiment

Mentality of designing of the present utility model is, installs a magnetic valve that is subjected to power supply control before the switch valve of gas-cooker at present additional, utilizes the timer and power supply (being generally No. 1 battery of 1 joint) the common cooperation of contact, realizes regularly.

Fig. 1 provides the schematic block diagram of each valve position, front and back on gas circuit, and magnetic valve 11 is arranged between kitchen range air inlet 13 and the switch valve 12, and two places sign 14 is switch valve large and small fire gas outlet among the figure.Promptly be the control circuit figure of this power supply magnetic valve among Fig. 2, this circuit comprises that the inductance coil L1 series connection of K switch 1 in power supply S, the timer and power supply magnetic valve forms.Fig. 3 is the timer gauge tap structural representation after repacking.This timer comprises a moving runner 36, one groove 35 is set on the outer peripheral face of this moving runner 36, the ledge 37 at control lever 34 middle parts of timer cooperates with this groove 35, inboard at movable contact spring 32, set up a fixed touching plate 33, K switch 1 among Fig. 2 is made of fixed touching plate 33 and movable contact spring 32, does not use former fixed touching plate 31.

Concrete operation principle is, in normal operation, timer switch button 59 among Fig. 5 is in the 0N state, ledge 37 among Fig. 3 on the control lever 34 leaves the groove 35 of moving runner 36, and movable contact spring 32 moves down, and movable contact 32 and fixed touching plate 33 disconnect, K switch 1 disconnects like this, therefore circuit shown in Figure 2 disconnects, and power supply magnetic valve 11 is in opening, and gas kitchen ranges uses according to existing mode.In case when the user determines to leave kitchen range that using or the culinary art of carrying out special time, start timer, be set a time rating, expire when time rating, the groove 35 of the moving runner 36 of timer turns to ledge 37 places of control lever 34, the ledge 37 of the control lever 34 of timer slips into groove 35 places of moving runner 36, the contact of fixed touching plate 33 is touched in the contact of movable contact spring 32 at this moment, contact switch K1 closure like this, coil L1 in the power supply magnetic valve obtains electric current, by electromagnetic induction, inhales the spool of moving electromagnetic valve 11, close gas circuit, realize timing function.This timer can be a mechanical timer, also can be electronic timer.

Another utility model that the utility model can be submitted to simultaneously with the applicant, the kitchen range that have again ignition function combine, at this moment circuit diagram is referring to Fig. 4, wherein K0 ' is the linked switch of Range switch valve, K switch 1 ' is identical with K switch 1 among Fig. 2, coil L1 ' is identical with power supply electromagnetic valve coil L1 among Fig. 2, and K switch 2 ' is again the normally closed switch that is controlled by the reed relay of thermocouple in the firing circuit, and K switch 3 ' then is made of fixed touching plate among Fig. 3 31 and movable contact spring 32.So the advantage that is provided with is, neither influences ignition function and timing function again, can not waste power supply to greatest extent again, concrete principle is that when not starting timer, K switch 1 ' is in off-state, K switch 3 ' is in closure state, as long as open Range switch, and linked switch K0 ' closure, circuit shown in Figure 4 is energising just, pulse igniter igniting, light a fire successfully after, the K switch 2 ' disconnection of controlling by thermocouple, pulse quits work, the protection power supply; After running into accident extinguishing, K switch 2 ' closure, impulse circuit still can be lighted a fire once more; after starting timer, in time rating, K switch 3 ' still is in closure state; do not influence ignition function again; and when expire time rating, by timer-operated switch schematic diagram 3 as can be known, this moment K switch 1 ' closure; coil L1 ' obtains electric current and makes power supply closed electromagnetic valve gas circuit; K switch 3 ' disconnects simultaneously, and do not close flame-out the generation and light a fire again because of gas circuit, thus the protection power supply.In addition; if igniting more after this; as long as timer is placed opening, auto-ignition combustion once more just, need console switch valve again; if do not need ignition; turn off the Range switch valve, K switch 0 ' disconnects, even not mobile timer; can not waste power supply yet, have the effect of protection power supply.

Fig. 5 is a vertical view of the utility model gas-cooker.From the outward appearance of figure, set up a timer switch button 59 in right eye kitchen range switch valve position, timing controlled right eye kitchen range.

Power supply magnetic valve of the present utility model is arranged between kitchen range air inlet and the switch valve air inlet, and the power supply magnetic valve can be arranged on the position between kitchen range air inlet and the kitchen range eye gas circuit branch crossing, and this moment, described timer was controlled all kitchen range eyes.The power supply magnetic valve can be arranged on after the kitchen range eye gas circuit branch crossing, and in the promptly single kitchen range eye air inlet, at this moment, timer is controlled the kitchen range eye on the described gas circuit.

More than all embodiment only for the explanation the utility model usefulness, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or variation, so all technical schemes that are equal to also should belong to category of the present utility model and should be limited by each claim.
